Up for sale is a Sunon fan that was in a Mesa Boogie Walkabout head. I had Mesa repair the fan in my Walkabout, but when I got the head back, I ended up taking it right out and replacing it with a Noctua fan. I believe it has a rating of 32cfm. The original wires were cut short when removed from the head, but I found the wires and soldered them back to the fan. Im practically giving this away for (almost) free, just pay the shipping and it is yours $5... PM me!!
